CAR-COUPLING.

SPECIFICATION forming part of Letters Patent N o. 51 1,042, dated December 19, 1893.

Application filed October 7, 1893. SerialNoASVAAB. (No model.)

To 0935 whom, it may concern:

Be it known that l, IRVIN L. BROWN, a citizen of the United States, residing at Waveland, in the county of Montgomery and State of Indiana, have invented a. new and useful Gar-Coupling, of which the following is a specification.

The invention relates to improvements lli car couplings.

The object of the present invention is to improve the construction of car couplings, and to provide one which will be capable of coupling automatically, and which may he readily uncoupled from the top and sides of a car, and which will not necessitate going between cars.

The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claim hereto appended.

In the drawings-Figure 1 is a perspective view of a car coupling constructed in accordance with this invention. Fig. 2 is a horizontal sectional view showing two drawheads coupled. Fig. 3 is a vertical sectional view.

Like numerals of reference indicate corresponding parts in all the figures of the drawings. I

1 designates a draw-head provided at one side ofa recess or opening 2 with an outward projecting arm 3, and having at the opposite side of the recess or opening an outwardly projecting portion 4 provided with a recess or cavity 5 at its inner side or face receiving a vertically disposed rotatively mounted compound knuckle 6, adapted to cooperate with a similar knuckle of a corresponding draw-head. The compound knuckle is pivotally mounted by a vertical pin 7, and is provided with a series of vertically elongated jaws 8, beveled at their outer sides. and having their inner sides or faces shouldered. One of the vertically elongated jaws projects at all times into the opening or recess 2 to interlock with a similar pro ecting jaw of a corresponding coupling and arranged adjacent to and in rear of the projecting jaw is a shoulder 9 of the draw-head,

which forms with the projecting jaw a rectangular recess for confining the engaging jaw of another coupling.

The compound knuckle is adapted to rotate rearwardly to permit, in coupling, the projecting jaws of two drawheadsto pass each other; and the knuckle is prevented from rotating forward and allowing the drawheads to separate by a hinged catch or pawl 10 mounted on a vertical pintle 11 and held in engagement with the knuckle by a spiral spring 12 arranged within a cap or cylinder 13, and having one end connected with the pintle, and its other end connected with or attached to the draw-head. The spring may be arranged at the top or bottom of the drawhead; the lower end of the pintle is threaded and provided with a nut or other means for retaining it in its perforation of the drawhead; and the upper end of the pintle is provided with an arm and may be connected by any suitable means with the top and sides of i a car to enable the operation of uncoupling to he performed from those points without going between cars.

It will be seen that the car coupling is sim ple and comparatively inexpensive in construction, that it is automatic in its operation, and that it does not necessitate persons going between cars. It will also be apparent that the vertically elongated jaws of the compound knuckle permit draw-heads to conple at different elevations.

Changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

What I claim is In a car coupling, the combination of a draw-head having a recess or opening and provided at one side of the same with a cavity and having a shoulder 9 arranged at the rear end of the cavity, a rotary compound knuckle mounted in the cavity and provided with a series of jaws beveled at their outer faces and having their inner or rear faces In testimony that I claim the foregoing as shouldered, said knuckle having one of its my own I have hereto affixed my signature in KO jaws projecting outward into the recess 01' the presence of two witnesses.

opening with its shonldered portion or face i T 5 arranged adjacent to the shoulder 9 of the IRVIN BROWL draw-head, a catch engaging the knuckle, \Vitnesses: and means for operating the catch, substan- WILL O. BUTCHER,

tially as described. JOSEPH R. SHARP.
